چکیده

Strains of the gastrointestinal species Lactobacillus reuteri were electrotransformed with plasmid constructs containing the endo-1,3-1,4-beta-glucanase gene (bglM) of Bacillus macerans. The enzyme was expressed and secreted by the lactobacilli. A plasmid construct containing the bglM gene lacking its promoter was derived and was demonstrated to be useful as a promoter probe vector.

Genes encoding xylan and beta-glucan hydrolysing enzymes in Bacillus subtilis: characterization, mapping and construction of strains deficient in lichenase, cellulase and xylanase.

The gene encoding extracellular xylanase (xynA) was amplified as a 770 bp DNA fragment from Bacillus subtilis 168 chromosomal DNA by PCR. The genes encoding endo-beta-1,4-glucanase (eglS) and endo-beta-1,3-1,4-glucanase (bglS) were isolated from a genomic library of B. subtilis 168. The sequences of xynA and eglS were identical to those of the xylanase and cellulase genes from B. subtilis PAP11...

Cloning and expression of endo-beta-1,3-glucanase gene from Flavobacterium dormitator in Escherichia coli and characterization of the gene product.

The beta-1,3-glucanase (1,3-beta-D-glucan glucanohydrolase, EC 3.2.1.6) gene from Flavobacterium dormitator var. glucanolyticae was cloned into Escherichia coli C600 with a vector plasmid, pBR322. The E. coli cells carrying a recombinant plasmid, pKU beta G1 (8.2 kb), showed a high beta-1,3-glucanase activity and a lytic activity on viable yeast cells. These activities were found in the peripla...

Properties of selected hemicellulases of a multi-enzymatic system from Penicillium funiculosum.

A multi-enzymatic system from Penicillium funiculosum displayed alpha-L-arabinofuranosidase, endo-1,4-beta-D-xylanase, beta-D-xylosidase and endo-1,3-1,4-beta-D-glucanase activities at high levels over a wide acidic pH range of 2.0 to 5.5. Moreover, the pH stability was particularly extended over the wide range of pH of 2.0 to 8.0 with endo-1,3-1,4-beta-D-glucanase and endo-1,4-beta-D-xylanase;...
